Answer 1

make print function in contact function which will accept 2 values and print that.

Check the given example in lesson to understand.

Answer 2

You should add a method to the constructor function like this:

function Car(){
this.drive = function(){
console.log("driving")
}
}

The drive function is a method just like print in your case and is called like this:

let a = new Car()

a.drive()

Hope this example helped.

😊
//code project (contact number) intermediate
//Javascript
//you need to add the print method inside the
// contact function (here it play the role of class).
// it is going to work as I wrote it down.

function contact(name, number) {
this.name = name;
this.number = number;

// add this print function to your code😎😊😊👇

this.print =function(){
console.log(this.name+": "+this.number)
}}
// ☝️☝️☝️

var a = new contact("David", 12345);
var b = new contact("Amy", 987654321);
a.print();
b.print();
